Because of the Oralce Bug #79989, there is no guarantee that after
including "ctype_common.inc" current value of the @@character_set_database
session variable will be 'latin1' and string literals without prefixes in the
following "SELECT" statement ('00' and '01') will have this charset.
As a workaround, we add explicit "_latin1" prefix to them.

Summary: MyRocks had a bug that checking tx isolation level happened twice per statement at external_lock(). This caused an unexpected error when setting prohibited isolation level (serializable or read uncommitted) as a session variable, and setting one shot read committed or repeatable read isolation level. Test Plan: issue314.test Reviewers: hermanlee4, jkedgar, spetrunia, mung Reviewed By: mung Subscribers: webscalesql-eng Differential Revision: https://reviews.facebook.net/D63915
